Penicillin resistance in pneumococci has slightly decreased due to vaccination.
Pneumococci mainly cause infections of the lungs (pneumonia) and blood (sepsis). The non-susceptibility rate to penicillin has decreased from 9.5% in 2004 to 6.3% in 2018. One reason for this trend is probably the pneumococcal vaccine. Since its introduction both the morbidity and the resistance rates have decreased considerably.

For this analysis invasive isolates (blood and cerebrospinal fluid) tested against the corresponding antibiotic (category) were considered only. If multiple antibiotics within the same antibiotic category were tested, the most resistant result was selected. In case of multiple isolates, the first isolate per patient, microorganism and calendar year was included only. Results are reported as delivered by laboratories. Statistics may be influenced by the changing number of laboratories participating. Data are provided for surveillance purposes and are not intended to be used for therapeutic decisions solely.
